C MPANY,-OF NEW YORK, N. Y., A CORPORATION OF DELAWARE.

Application led June 7,

To all whom it may concern:

Be it known that I, Alrrnun A. JoHNsoN, a citizen of the United States, residing in borough of the Bronx, in the county of the Bronx, city and State of New York, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a Specification.

This invention relates to an improvement in typewriting machines, and more particularly to means for enabling various worksheets to be collated upon one another to rcceive typeimpressions from the machine.

In the present invention, a table located above the platen at the delivery side thereofs is provided with means to enable the collating of worksheets placed in th(I machine. This collating table extends a considerable distance up from the platen so that large sheets may be used. v

To introduce the work-sheets into a type- `writing machine, the operator usually places the leading edge of the sheet on the paper table at the rear of the machine, and then moves the sheets around beneath the platen. The sheets are placed face downward, so that when moved around to printing position the face will be up to receive type-impressions.

To facilitate the insertion of the worksheets, the present invention provides means whereby the sheets may be inserted from the front of the machine. This arrangement relieves the operator of the necessity of reachingover or around the collating board. lo introduce the sheets to the machine. The operator instead introduces the sheets from the front of the machine. With this arrangement the sheets are at all times face upward` and therefore may be more easily collated.

This arrangement also enables the operator to readily collate the sheets individually; that is, onevof the sheets, may be placed in the machine and. positioned upon the collating table, so that the first line to be written upon' is at the writingdine, and the'pext sheet with a carbon may be placed in'the machine and collated, so that its first line to be written upon is at the writin line Vand so on until the sheets are assemblged.y IThe arrangement is such, that the worksheets may be engaged by the feed rolls While still in the original collated position on the collatiug table.

It is sometimes desired that checks or other small work-pieces be collated with Speci'cation of Letters Patent.

larger work-pieces. These small work-pieces are usually so small as not to extend up to the collating table. For the purpose of collating these small work-pieces and for other purpses, the present invention provides eollating devices directly upon the platen. These collating devices on the platen may be used tothe exclusion of the collating ydevices on the table, under some circumstances, and the collating devices on the table may also be used to the exclusion of the collating de vices on the platen. Both collatin devices may also be used simultaneously w en it is desired to collate both small and large Worksheets.

ln the present invention, the collating table located above the platen or on its de livery side is provided with collating devices in the form of a. series of studs arranged in rows, one row at each side of the collating table, in position to be engaged by erforations in the work-sheets. These stu s ure arranged so that they are normali in an ineffective position below the sur ace of the paper table, to permit free movement of the work-sheets during the course of Writing. The studs are arranged to be manually or automatically protruded through the collating table when it is desired to collate the sheets thereon.

To facilitate the insertion of the sheets at the front of the machine, the platen may be arranged to be movable upward and away from the type guide, the ribbon vibrator and other parts, usually found in visible typewriting machines, that obstruct the free ssage at the front of the machine of the ttom edge of the sheet. To guide theworksheets past these and other obstructions to the usual paper apron beneath the platen, an auxiliary paper guide may 'be provided. This paper guide may be arranged to normally occupy a position ofdjisuse' or retire-` ment beneath the platen, and the arrangement may be such that when the platen is moved to apar-receiving position, the auX- iliary gui e or directrix' is moved u to posh tion to properly guide the bottom e ge of the sheet into the machine. This auxiliary guide may be provided with a scale or means along its top edge for indicating the portion of the platen which will be the Writing line when the platen is returned to normal Writing position. To permit this movement of the platen, the platen may be mounted in a frame,

which, in turn, is pivotally mounted in a platenshift frame of the ordinary typewriter carriage, and this arrangement will not in any way alter the action of the usual case-shift mechanism.

The collating studs are projected automatically to an effective position after the usual feed rolls have been released when the platen moves to receiving position.. This may be done by providing a connection hetween the movable platen and the collating studs, which act through the medium of the feedwoll release mechanism, so that the feedroll release and the movable platen jointly control the colluting pins. This is done so that the collating pins will only be projected by the movements of the platen when thc feed rolls are released, and so that when the feed rolls are again caused to engage the platen, while the platen is still in receiving position, the eollating studs will be retracted.

The eollating studs on the platen may be. arranged in rows, each row being in line with a row of studs in the collating table. There may la. one pair of collating pins for each line of writin ion the platen. A finger-piece may be provi ed so that, when operated, only the row at the writing line will be prot ruded for collating purposes. The tops of these studs may be normally flush with the platen.

The connections between the platen and the line-space mechanism may be maintained during the movements of the platen for reeeiving the sheets by in'eans of a pair of gears meshing with an intermediate pinion.

Gther objects and ladvantages will hereinafter appear.

"ig, 9 is a detail view of the pressure feed-rolls, showin the means of locking them inl their position away from the platen, so as to prevent their accidental rengagement with the laten. The locking means also prevents t e accidental retirement of the collating studs to an ineffective position.

The platen 1 is mounted on an axle 2, which is supported to rotate in an auxiliary frame il. The auxiliary frame 3 is mounted to swing about axially alined stub shafts 4, which, in turn, are n'lounted on the usual platen frame 5. The platen frame fris sup ported by the carriage (i, which travels in the usual way on the usual rail at the front of the ma chine. For the purpose of shifting the platen frame 5 and with it the auxiliary platen frame 3 am the platen 1, there is provided the usual case-shift frame 8, whereby both upper and lower-case characters may be written by the type-bars indi` cated in dotted lines at 9, Fig. 2. The platen frame 5 is supported in the way common to an Underwood typewriting machine, which includes rollers l() riding on the rail 11' of the case-shift frame 8, and swinging armsl 12 pivoted on the carriage at` 13 and engaging studs 14- provided on the platen frame 5.

In order to rotate the line-space mechanism, there is provided a supplementary axle 15 mounted in the platen frame 5, normali in line with the laten axle 2, but not integral therewith. Ihis supplementary axle I5 may be turned by a knob 1G thereon for a number of linespaces back or forth, and may also be operated by the usual line-space mechanism for line-space movements of the platen predetermined extents. This line-spuce mechanism includes a line-space lever 17, Fig. 6, and is ot' atype common in Underwood typewritiug machines. The line-space lever 17 is connected to operate a slide 18, which carries a pawl 1t) to drive a ratchet. wheel 2t). The ratchet wheel 20 is secured to the su plementary axle 15.

n order that the platen 1 may be driven from the supplementary axle 15,v which re ceives said movements for linespacing the platen by thel usual on the rail 7 at the rear, and

platen, from tHe lmob 16 and lever 17, there 1s provided a train of gearing which connects the supplement-ary axle 15 with the platen axle 2. This train of gearing 1ncludes a. gear 21, secured to the'snpplementary axle 15, driving a broad pinion 22 meshing with and driving a gear 23 corresponding to the ear 21, ut secured to the platen axle sha t 2. The pinion 23.15 mounted .for bodily rotation (zo-axially with the shaft 4, so as to permit the swin ing of the laten with the gear 23 about t ie axis of tie shaft 4 without interfering with the driving connection from the platen to the` knob 16 and the line-space mechanism. Thus the proper relation between the platen and linespace mechanism is constantly maintained.

The right-hand end of the platen axle 2 may proJert, as seen in Fig. 1, and be`pr0- vided with a knob 24 similar to the knob 1li. l 'ro vision is made for permitting a relative motion belween this portion of the platen axie 2 and the platen frame 5, by Cutting away the latter. as indicated in Fig. 4 at 25, to form a slot of suiliciemt length to allow for the relative up-anddown movement of the platen i with respect to the platen frame 5,

The platen frame 5 is provided with the usual paper-apron 2G, whereby the Worksheet may he inserted on the platen from the rear for any ordinary typewriting if deaired. The platen shield 27 takes the paper, when inserted from the rear, from the paper-apron 26 and guides it around the platen. When the platen is rotated, feeding the paper around with the platen is acconr plished by means of ihe usual pressure feedrolls 28 and 29 mounted on swinging frames 30 and 3i, which are mounted on a rod 31 seemed to the auxiliary frame 3. Normally. springs 32, Figs. l and 9, urge the pressure feed-rolls 28 and 29 into close contact. with the platen 1 or Work-sheets 'carried thereby.

To spread the rolls 28 and 29 apart from the platen, and thus enable the work-sheet to be readily placed upon the platen, a eedroll release Luger-piece 33 is provided. This finger-piece, when depressed, rocks about a pivot 34- :o draw up on a link 35, so as to rock the arm 36 secured to a rock shaft 37. The rock shaft 37 is provided with flat sides 38 and 39 at intervals, which, when the rolls are in gripping relation with the platen, are

adjacent the inner sides of arms 40 and 41 secured, respectively, to the frames 30 and 31. When. the release linger-piece 33 is de- `messed, however, the rock shaft 37 turns in lts bearings, to bring the other sides 4,2 and 43 thereof into engagement with the inner sides of the arms 40 and 41, thereby spreading the arms 40 and 41 apart, inasmuch as these sides 42 and 43 are located at greater 1,278, uis

distances from each other than, the sides 38 and 39. The spreading of the arms likewise preads the frames 30 and 31, so as to withraw the pressure rolls 28 and 29 from cooperative relation with the platen 1.

It will be noted in passing because of the flat sides 42 and 43, that the pressure feedrolls 28 and 29 are looked in their disengaged position, and can only be restored by a posiv tive return of the release finger-)ieee 33. .The paper shield 27 is supported'on the auxiliary frame 3, so that it will move with the pressure feed-rolls 28 and 29 and the platen 1 when said .auxiliary frame 3 is moved.

Normally, the auxiliary frame 3, together with the platen 1, is held in a` depressed position, corresponding to that of Figs. 1, 2 and 4, by means of a latch 44 carried there by, which engages a pin 45 carried by the platen frame 5. Springs 46 act to swing the auxiliary frame 3 about its pivot 4 when the latch 44 is released by a depression of a finger-piece 47, carried thereby. The latch and its finger-piece 47 are integral, so as to move as a unit. To operate the release key or finger-picco 33, by the operation of the finger-piece 47, n pin 48 thereon overlies and engages the lever of the release key 33. The member 47, on which the latch 44 is formed, is formed so as to permit an extra movement thereof relative to the pin 45, for the pur pose 'of operating the release key 33. That is to say, there is provided a cut-out portion 49, Fig. 3, which is bordered on the opposite side from the latch 44 with an extension 50 limiting the movement of the finger-piece 47. A spring 51 automatically returns the finger-piece 47, and the latch 44, as they are integral, when the pressure thereon is released. This return, however, only brings the parts to the position of Fig. 3, as, in order to rengage the latch 44 with the pin 45, it is necessary to depress the platen Il and its auxiliary' frame 3 against the tension of the spring 46, as for instance, by means" of a hnndhold 52, Fig. 6.

It will thus be seen that with the raising of the platen 1 to a position to permit the insertion of the work-sheets at the front the-r of, the pressure feed-rolls 28 and 29 arera so moved to their inactive position and locked in this position.

To assist in guiding the work-sheetson the platen 1 from the front, there is provided an auxiliary guide53, which is in the form of a bail swingingly mounted on the platen axle 2 and forming an extension of the paper shield 27. The upper edge of the guide 53, indicated at 54, may be used to act as an auxiliary line gage, inasmuch as the platen 1, when moved to its oollating position. moves away from the usual line gage indicated at 55, Fig. 2. The guide 53 also helps the lower edge of the work-sheets fio in clearing the ribbon and its supporting mechanism indicated at 56, Fig. i2, which usually obstruct the insertion of sheets bottom first at the front of the platen. The usual ribbon is indicated at 5G, threaded through a vibrator 56".

The guide 53 is normally in a depressed position when typewrlting, so ne to clear the line gage 55, the ribbon mechanism 5G and the type-bars 9. When collating, however, the guide 53, bein mounted on the platen .axle 2, mover-iI up with the platen at the same speed as the latter for a portion of the platens movement. In order to move this guide 53 an added amount so as to bring its upper edge nearer the top of the platen, it has an accelerated movement during the latter portion of the upward movement of the platen. For thispurpose, there is provided an arm 57 on the bail of the guide 53, which extends rearwardly from the platen axle 2 to such a position as to engage a fixed pin 58 secured to the platen frame 5, and relatively to which the auxiliary frame 3 swings. That is to say, the auxiliary frame il is provided with a slot 5U into which the pin 5H projects, permitting the auxiliary frame -l to swing upwardly. The arm 57 of the guide 53 overlaps the lower portion of the slot 59, as indicated in Fig. 2, .so that during the latter portion of the upward movement of the frame 3 and the platen 1, the arm engages the pin 58 and is -swung relatively to the frame 3 against the tension of a Spring (i0, which normally holds the guide 53 in its lowermost position. Thus, the pin 5S causes the guide 53 to swing about the platen axle 2, so as to raise the upper edge of the guide 54 higher than it would iiu it depended only on this movement with the platen and the auxiliary frame 3. rlhisenabhu-` the easy insertion ot' the Mrk-sheets on the platen from the front, hy guiding the lower edges of the work-sheets around the platen to the bite of the eed-rolls.

When eollating work-sheets, such as bills, of fair size, a collating board 61 is used, which extends upwardly from the front side of the platen to 'a position considerably above the same; This collating board 61 is provided with studs (32 on each side thereof. to engage perforations provided in the side margins of the work-sheets. Normally, these studs (3Q are receded below the face of the collating board (il, as in Fig. 2, so that they will not obstruct 'the movement of the work-sheets,l as they come from the platen in a normal typewriting operation. When the platen 1 is raised to a collatin'g position, howeverg'the Studs 62 are also projected to an effective collating position.

Tfhe `studs 62 aremounted on blocks 63, which are guided for movement by the Studs 62 themselves` extending through perfora- .tions 64 in the. collating board 61. These blocks (33 are manipulated by a Slide 65, which has inclined cam slots 66 engaging pine` (i7 provided on the blocks (i3. Normally, a spring (38 holds the slide 65 in such position that the pins (57 will be yin the upper portions of the cam slots '66, as in Fig. 2, .so that the blocks will be held in their rearmost position and the studs 62 likewise held in a rel-edad inelfeotive position.

The Slide 65 is moved against the tension of the spring 68 through the medium of the feed-roll release key 33, which, it will be re membered, is operated when the laten is shifted to its upper collating position. For this purpose, the rear arm (19 ol the release key 33 is provided with a pin which .extends into a slot 70, Figs. 2 and 3, in a link 7l connected to the slide (35.

The releasing movement of the key 33 will be idle with respect to the link 71, because of the slot 70, so that the rolls 2H and il!) will lbe Withdrawn from the platen licfore the Studs (l). are projected. When thc key 33 now movers' upwardly, with the release auxiliary` frame, it will 'force the slide 65 upwardly against the tension of its, spring Go? to the Fig. 3 position, when the studs 62 will be camined to their projecting position. This lost motion between the release key 33 and the slide 65 enables the studs 62 toY he moved out of the perforations in the work-.sheets after collating of the worksheets, when the pressure feed-rolls 28 and Ztl are brought into play to grip the worksheets to the platen, but before the platen is returned to normal position, thereby preventing the tearing of the work-sheets, due to a premature returning of tnc platen to norinal position.

vinasmuch -as the feed-roll release key 35i projects the studs (32 against the tension of the spring (i8. a utility of the locking action provided by the Hat sides 42 and 43, Fig. 9, is seen. These flat .sides will positively lock the studs in theirplbjected position, and the feed-rolls in their released position until the operative restores the release key 33 to its normal position.

lVhcn collatin small work-sheets, such as bills or checks, w iich will not bridge the dietanre. from the platen to the lower studs (i2 on the collating board, platen-carried studs 72 are used. There are two series of these studs, one on each end of the platen, and there is one stud in each series for every linespace of the platen. Normally, the studs 72 are recededv within the platen to a position such that their outer ends are Hush with the platen, thereby forming a continuous surface. The pair of studs which will bring to the printing oint the initial lines of Writing of short billns or sheets, may be pro'ected to permit perforations in these short bills or sheets to engagethe studs for arranging them relative to each other or :to'larger work-sheets collated on the studs 62.

i For this purposefeach air `of studs 72, in addition to being guided) by radial openings 73 in the platen 1, is connected to a `shift bar 74. Each of the studs 72 is pro-V vided with an inclined groove 75, Figs. 5 `and 6, which engages a camming section 76 inclined to the general length of the bar 74, and formed `by cutting out notches in the opposite edges of the bar. When the bar 7 4 is moved endwise or lengthwise of the platen, it shifts a air of the studs 72. The normal position o the studs and the bar is shown in- Fig. 5, which position is maintained by the arms of a spider spring 77.

When necessary to project a pair of the studs or pins 72, a shift lever 78, Figs. 1 and 8, is swung about its pivot, so as to bring a cam 79 thereon into engagement with the projecting end 80 of the particular bar 74, corresponding to the line of .Writing of the laten. This shifter will thus force the ai' 74 from the Fig. 5 position yto ther/Fig. 6 position against the tension f the spring 77, thereby protrudingthe pair ofthe collatin' studs 72 which happen to correspond wit the line of writing, or, at least, correspondiii .to perforations in the work-sheets, which wi 1 bring the desired lines of writing in register with each other, and in register with the printin point of the typewriter. It will be note that the bars 74 are made of flexible material, so that the collating 'studs 72 may be inserted through their openings 73 and readily cam aside the'bars 7i to 'engage their notches 75 with the .cam sections 76. This 4enables the mechanism to be rapidly assembled. The pins `72 are cam- Ashaped at 81 for this purpose. The projection ofthe bars 74 at both ends through slots in the end plates of the platen prevents their getting out of position, and guides them in their movement.

The slide 65 is justified in its up-and-down movement, so as to project the collating board studs 62 evenly on opposite sides, by means of a pair of gears 82 secured to a shaft 83, Fig. 1, and engaging racks 84 provided oii the slide 65. Y

The operation of the device will be readily understood when taken in connection with the above description. For collating or assembling two or more work-sheets, such as bills or the like, Yso that diercntly located lines will' coincide with each. other, the platen 1 is raised by operating the Vfinger-piece 47 to release the latch 44. This enables the spring 46 to lift the platen, so as to space it relatively tolthe line gage 55 and the ribbon mechanism 56. 1

The finger-piece 47. through the intermediary of the pin 48, operates therelease key 33 to rrelease the pressure feed rolls 28 and 29. 'i The upward movement of the platen whereby the work-sheets may be inserted I on the platen from the front.

The extent of insertion of the work-sheets,

land thus the assembling to bring the desired lines on different sheets in register with each other, may be determined by placing them on the studs. 62, which have been projected with the upward movement of the platen. The work-s eets may be rovided with per-` forations on either one side or the other or on both sides, so as to coperate with one or more, preferably two, of the studs 62.

When the sheets have been assembled in this way, so as to bring predetermined lines on the different sheets in register with each other, then the platen can be restored to its normal first position by pressure on the finger-piece 52. Prior to this return movement, the release key 33 is raised so as to unlock the pressure rolls 28 and 29 and bring them to an effective position. The restoration of the finger-piece 33 permits the Withdrawal of the studs 62 by means of the s t e pressure rolls engage the platen, so that the sheets will be held by the feed-rolls on the platen just as they were when the studs 62 were in engagement with the work-sheets, thereby eliminating the danger of disarrangement of the work-sheets.

If short work-sheets. such as bills or checks, are to be collated and printed upon, the length may not be such` as to reach the studs 62. In such a case, the platen-carried studs 72 are used. These studs, which are mounted `at the ends of the platen outside of the printing field thereof, are projected in airs, one pair at a time, by the handlcver 8, so that they lmay engage properly-positioned rforations provided on the bills or checks bin assembled. When the platencarried stu s 72 are used, the platen 1 may be raised as before, with the raising of the guide 53, so that the bottom edges of the work-sheets can be readily inserted on the platen at the front.

The hand-lever 78 may be retained in any of its positions by a detent spring 85 co operating with holes or depressions 86, Figs. 6 and 8, formed in .the auxiliary frame. 3.

I With the above arrangement, it will be seen that it is possible for the o erator to col ,te the sheets individually; t at is, one of le sheets may be introduced `between the pla n and the feed rolls, from the front, by means of the shield 53, and thcn collated upon the studs 62. so that the first line to be 'written upon is in line with the gage 54.

pring 68 to an ineffective vposition after asi,

' bling the sheets on 4o bo suporting `said platen, means Then the second sheet isr introduced by the Shield 53, and in a like manner collated upon `studs 62, so that its first upon is in line with the gage 54, and so on, until various sheets are collated. This methodr of handling the sheets is of reat ad-4 vantage, especially where some of t e sheets are left in the machine to make a record of all the transactions which take place, such as in condensed billing. It is also an advantage, in that the operator, during a eollating operation, hasthe working faws of the sheets in full view.

cn a check or other small work-piece is to, be collated ,iipon the pins 72 carried by` the platen, the .said small work-piece will be introduced to the platen while the studs 72 are in a retracted position within the platen. After thework-pim-es have been placed in the machine, the eollating studs in the platen are protruded by means of theIinger-piece 78. The sheets are then pins.
